    • PURPOSE: An apparatus for generating multi-wavelength light is provided to have high single mode stability and high yield according to transmission spectra, reduce light loss, improve element reliability, and increase the coupling efficiency of lights. CONSTITUTION: A high reflective coating film(110) is formed on a cross-section of a gain portion(120). The high reflective coating film can be composed of mirror elements having high reflection or a metal or dielectric thin film coating surface. The gain portion generates multi-wavelength lights. Each channel included in the gain portion includes a gain waveguide for providing gains to generated light. A reflecting portion(130) again reflects the lights entering from the gain waveguide to the gain portion. A multiplexing portion(140) multiplexes single mode lights generated in each channel of a distributed bragg reflector laser.
